Q
Q: If a circuit has a total resistance of 10 ohms and a current of 3 A flows through it, what is the voltage across the circuit? (2020)
Solution:
Using Ohm's law, V = I × R = 3 A × 10 Ω = 30 V.
Steps: 5
Show Steps
Step 1: Identify the values given in the problem. We have a total resistance (R) of 10 ohms and a current (I) of 3 A.
Step 2: Recall Ohm's law, which states that Voltage (V) = Current (I) × Resistance (R).
Step 3: Substitute the values into the formula: V = 3 A × 10 Ω.
Step 4: Calculate the voltage: 3 A × 10 Ω = 30 V.
Step 5: Conclude that the voltage across the circuit is 30 volts.
