Question

1. current flow in a circuit can be calculated by:

ca. dividing ohms by volts.
cb. multiplying amps times ohms.
cc. dividing volts by ohms.
cd. multiplying volts times amps.

Explanation:

Ohm's Law states that \(I=\frac{V}{R}\), where \(I\) is current (in amps), \(V\) is voltage (in volts), and \(R\) is resistance (in ohms). This formula shows that current is calculated by dividing volts by ohms.

• Option A: Dividing ohms by volts (\(\frac{R}{V}\)) is not the formula for current.
• Option B: Multiplying amps times ohms (\(I\times R\)) gives voltage (\(V = I\times R\)), not current.
• Option C: Dividing volts by ohms (\(\frac{V}{R}\)) is the correct formula for current according to Ohm's Law.
• Option D: Multiplying volts times amps (\(V\times I\)) gives power (\(P=V\times I\)), not current.

Answer:

C. dividing volts by ohms.
