Q: If a circuit has a total resistance of 8Ω and a current of 2A flows through it, what is the voltage across the circuit? (2020)
Solution:
Using Ohm's law, V = I * R = 2A * 8Ω = 16V.
Steps: 5
Show Steps
Step 1: Identify the values given in the problem. We have total resistance (R) = 8Ω and current (I) = 2A.
Step 2: Recall Ohm's law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 2A * 8Ω.
Step 4: Calculate the result: V = 16V.
Step 5: Conclude that the voltage across the circuit is 16V.
