What is the effective value of resistance when two resistors 10 ohm and 20 ohm are connected in parallel combination?
Therefore, the effective resistance in the circuit is 4.615 ohm .
What will be the power consumed in a resistor of 10 Ohm if it is connected across 20 V supply?
Total resistance (R) = R₁+R₂ = 10+20 = 30Ω Power consumed (P) =?
How do you find the potential difference across a 10 ohm resistor?
Answer
- Solution:
- Properties of a series circuit :
- Potential Difference = 2 V.
- Current =?
- Net Effective Resistance = 10 Ω + 5 Ω = 15 Ω
- Hence the current in the series circuit is 0.13 A.
- Hence the potential difference at the 10 Ω resistor is 1.3 V.
When two equal resistance of 10 ohm are connected in parallel what will be the effective resistance?
What is the effective resistance when two resistance of 10 ohm and 15 ohm are connected in parallel? Equivalent Resistance = 6 Ohm . This is the required answer .
When two resistance are connected in series What is the potential difference across two resistance?
Series Resistor Equation If two resistances or impedances in series are equal and of the same value, then the total or equivalent resistance, is equal to twice the value of one resistor.
What is the potential difference across the 20 ohm resistance in the circuit?
Potential difference across 20 Ω resistor is 20 Volt.
How do you find potential difference?
Multiply the amount of the current by the amount of resistance in the circuit. The result of the multiplication will be the potential difference, measured in volts. This formula is known as Ohm’s Law, V = IR.
When two resistors are connected in series the answer is the same across each resistor?
. Since there is only one path for the charges to flow through, the current is the same through each resistor. The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances.
What is the potential difference across resistor?
The potential across a resistor, also known as voltage drop, describes how much of the supplied energy of a voltage source is reduced when a electric current goes through a passive element, in this case the resistor.
