Question

A circuit is built based on the circuit diagram shown.

What is the current in the 50 Ω resistor?

A) 1.2 A
B) 1.5 A
C) 2.0 A
D) 4.6 A

Answer 1

The current in the 50 Ω resistor is A) 1.2 A

Answer 2

The correct answer is A

Step-by-step explanation:

The diagram provided is that of resistors connected in parallel since each individual resistor is directly connected to the 60 V voltage source.

In order to calculate the resistor's current (in amphere, A) in the 50 Ω resistor, the resistor's voltage (in volts,V) is divided by the resistance (in ohms, Ω).

Hence,

Current = voltage ÷ resistance

The voltage is provided in the diagram to be 60 V

Current = 60 ÷ 50

Current = 1.2 A
