Find the current through the 30 Ω resistor in the circuit shown.
Correct answer: D. 5/6 Ampere
- A. 2/6 Ampere
- B. 3/6 Ampere
- C. 4/6 Ampere
- D. 5/6 Ampere
Explanation
To find the current through the 30 Ω resistor, you need to determine the potential difference across it. The given potentials are 10 V and -15 V. Thus, the potential difference is 10 - (-15) = 25 volts. Applying Ohm's Law, I = V/R, where V is the potential difference and R is the resistance (30 Ω), we find the current I = 25/30 = 5/6 A. Therefore, the correct answer is 5/6 Ampere.The other options (2/6, 3/6, and 4/6 Ampere) do not result from the correct calculation using the given potential difference, indicating errors in those potential difference values or arithmetic operations.

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.
