## How do you find the current between a resistor and a battery?

In this case the current supplied by the battery splits up, and the amount going through each resistor depends on the resistance. If the values of the three resistors are: With a 10 V battery, by V = I R the total current in the circuit is: I = V / R = 10 / 2 = 5 A.

**What is the potential difference across 2 ohm resistor in the given circuit?**

(d) Since it is a balanced Wheatstone bridge, potential difference across 2Ω resistance is zero.

### What is the current passing through the 5.0 ohm resistor?

2.4 amperes

The current through the 5-ohm resistor is 2.4 amperes.

**What is battery current?**

Current = the number of electrons that happen to be passing through any one point of a circuit at a given time. The higher the current, the more work it can do at the same voltage. Power = voltage x current.

#### What is current through the battery?

The voltage of a battery is also known as the emf, the electromotive force. This emf can be thought of as the pressure that causes charges to flow through a circuit the battery is part of. This flow of charge is very similar to the flow of other things, such as heat or water. A flow of charge is known as a current.

**How do you calculate resistors?**

To calculate the total overall resistance of a number of resistors connected in this way you add up the individual resistances. This is done using the following formula: Rtotal = R1 + R2 +R3 and so on. Example: To calculate the total resistance for these three resistors in series.

## Which resistors in the circuit are connected in series?

When two or more resistors are connected together end-to-end in a single branch, the resistors are said to be connected together in series.

**How do you find the potential difference across a resistor in Class 10?**

Then the individual voltage drops across each resistor can be simply calculated as: V = I*R where R represents the resistance value.

### What is the potential difference when resistors are connected in series?

If more resistors are connected in series to the circuit then different voltages will appear across each resistor in turn with regards to their individual resistance R (Ohms Law I*R) values providing different but smaller voltage points from one single supply.

**What is the current through a 10 Ω resistor when a voltage of 5.0 V is applied across it?**

Explanation: 10/5= 2 Current =2 amperes.

#### What is the current through the 3.0 Ω resistor?

The current through the 3.0 Ω resistor is 2.0 A.

**What happens when a battery is connected to a resistor?**

2. A battery is connected to a resistor. Increasing the resistance of the resistor will A. increase the current in the circuit. B. decrease the current in the circuit. C. not affect the current in the circuit. 3. A battery is connected to a resistor. As charge flows, the chemical energy of the battery is dissipated as A. current.

## How many resistors does it take to power a 9v battery?

A battery with a terminal voltage of 9 V is connected to a circuit consisting of four 20-Ω and one 10-Ω resistors all in series ( Figure 10.13 ). Assume the battery has negligible internal resistance. (a) Calculate the equivalent resistance of the circuit. (b) Calculate the current through each resistor.

**What is the power dissipated when a resistor is connected?**

A resistor is connected to a 3.0 V battery; the power dissipatedin the resistor is 1.0 W. The battery is traded for a 6.0 V battery. The power dissipated by the resistoris now A. 1.0 W B. 2.0 W C. 3.0 W D. 4.0 W Multiple choice Problem 1: An electric blanket has a wire that runs through the interior.

### How do you calculate the resistance of a resistor in parallel?

Resistors in parallel formula. The units of all values are Ohms (symbol: Ω). 1 Ohm is defined as electrical resistance between two points that, when applied with a potential difference of 1 volt, produces a current of 1 ampere. Hence, 1Ω = 1V / 1A or, in SI base units, Ω = kg * m^2 / (s^3 * A^2).
