Step-by-Step Verified Solution

To determine the current through the battery in this circuit, we need to consider the equivalent resistance and the biasing of the components involved.

Both components in the circuit are forward-biased. Given this, the equivalent resistance ( ReqR_{\text{eq}} ) is 10 Ω10 \, \Omega .

The current ( ii ) through the circuit can be calculated using Ohm's law:

i=VR=5 V10 Ω=0.5 Ai = \frac{V}{R} = \frac{5 \, \text{V}}{10 \, \Omega} = 0.5 \, \text{A}

Thus, the current through the battery is 0.5 A0.5 \, \text{A} .
