Question

If the resistance of an electric iron is 40 and a current of 2.2 A flows

through the resistance. Find the voltage between two points. *

Answer 1

88 volts

Step-by-step explanation:

Ohm's law gives the formula : I = V/R

In this case, since we are solving for voltage, you simply rearrange the equation to be : V = I * R

Therefore, given the resistance and current, you just plug in the numbers.

Voltage = 40 ohms * 2.2 amperes

Voltage = 88 volts
