Find the resistance if voltage of the circuit is 45 volts and current 30 Amp.
Correct answer: B. 1.5 ohm
- A. 1.6 ohm
- B. 1.5 ohm
- C. 1.7 ohm
- D. 1.8 ohm
Explanation
R = V / ISubstituting the given values, we get:R = 45 V / 30 A = 1.5 ohmTherefore, the resistance of the circuit is 1.5 ohm

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.
