a circuit is built based on the circuit diagram shown. what is the current in the 50 ω resistor? 1.2 a 1.5 a…

Explanation:

Step1: Apply Ohm's law for parallel - circuit

In a parallel - circuit, the voltage across each resistor is the same as the source voltage. Here, the source voltage $V = 60$ V and the voltage across the $50\ \Omega$ resistor, $V_{50}=60$ V.

Step2: Calculate the current through the $50\ \Omega$ resistor

According to Ohm's law $I=\frac{V}{R}$, where $V$ is the voltage across the resistor and $R$ is the resistance. For the $50\ \Omega$ resistor, $R = 50\ \Omega$ and $V=60$ V. So, $I=\frac{V}{R}=\frac{60}{50}=1.2$ A.

Answer:

1.2 A
