Question
Suppose you have a simple circuit that includes a resistance device of 75 ohms, and the current flowing through it is 2.0 amps. Calculate the voltage of the battery.
Solution
To calculate the voltage of the battery, you can use Ohm's Law, which states that the voltage (V) across a resistor is equal to the current (I) flowing through it times its resistance (R). Mathematically, this is expressed as:
V = I * R
Given in the problem, the resistance (R) is 75 ohms and the current (I) is 2.0 amps. Substituting these values into the formula gives:
V = 2.0 amps * 75 ohms = 150 volts
So, the voltage of the battery is 150 volts.
