Question

What is the current in the 10.0 Resistor?

A. ) 10.0 A
B. ) 2.00 A
C.) 12.0 A
D.) .0833 A

Answer 1

option B .

Step-by-step explanation:

Here all resistors are connected in series to a potential of 120V .

So here the net resistance would be the sum of all resistors,

= 10 + 20 + 30 = 60Ω

By Ohm's law ,

Voltage = current*resistance

on substituting the respective values, we have ;

120 = I * 60

I = 120/60

I = 2 A

In series current flow is same through all resistors so , the current 10Ω resistance is 2 amperes.
