Answer:
Equivalent resistance: 2.73 Ω
Voltage: 120 V
Total current: 44 A
Step-by-step explanation:
In the figure attached, the circuit is shown
The equivalent resistance (Rt) is calculated as follows:
1/Rt = 1/R1 + 1/R2 + 1/R3
where R1, R2 and R3 are the individual resistances. Replacing with R1 = 5 Ω, R2 = 10 Ω and R3 = 15 Ω, we get:
1/Rt = 1/5 + 1/10 + 1/15
1/Rt = 5.5/15
Rt = 15/5.5 = 2.73 Ω
From the picture, the voltage in the circuit is 120V
From Ohm's law:
It = V/Rt
where It is the total current, V is the voltage and Rt is the equivalent resistance
It = 120*5.5/15 = 44 A
