Resistors of 5 ohm and 10 ohm are connected parallel. If the potential difference across 5 ohm resistor is 20 volt then current through 10 ohm resistor will be:
Correct answer: E. 2 ampere
- A. 30.5 ampere
- B. 20 ampere
- C. 4 ampere
- D. 10 ampere
- E. 2 ampere
Explanation
When resistors are connected in parallel, the potential difference across each resistor is the same. here,, the potential difference across the 5-ohm resistor is given as 20 volts. Using Ohm's Law (V = IR), we can find the current through the 10-ohm resistor: V = IR 20 V = I * 10 Ω I = 20 V / 10 Ω I = 2 A As it is a numerical only one option E is correct.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
