Question

In a simple circuit a 6-volt dry cell pushes charge through a single lamp which has a resistance of 3 Ω. According to Ohms law the current through the circuit is _____________ Amps.

Answer 1

2 Amps

Explanation:

Given:

Voltage (V) = 6 V

Resistance (R) = 3 Ω

We calculate the current using Ohm's law, like this:

`\begin{gathered} I=(V)/(R) \\ \\ \text{ We replacing:} \\ \\ I=(6)/(3) \\ \\ I=2\text{ amps} \end{gathered}`

The current through the circuit is 2 Amps
