The current in the 2nd case is 102 A
Step-by-step explanation:
The relationship between voltage, current and resistance in an electric circuit is given by Ohm's law:
where
V is the voltage
I is the current
R is the resistance
In this problem we are given two sets of data for the current and the resistance, while the voltage is kept constant. This means that we can write:
where
is the current in the 1st case
is the resistance in the 1st case
is the resistance in the 2nd case
Solving for , we find the current in the 2nd case:
