A resistance of 40 Ohms is attached to a circuit having current of 300 Amperes. Find the voltage:
Correct answer: A. 12,000 volts
- A. 12,000 volts
- B. 15,000 volts
- C. 20,000 volts
- D. 300 volts
Explanation
Resistance=40 ohms Current=300 A Voltage=?By ohm's law; V=IR V=(300)(40) V=12000 VHence,A is the correct option.

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.
