### FCC Technician Exam Question Of The Day (T5D09)

Q) What is the current flowing through a 24-ohm resistor connected across 240 volts?

A) 10 amperes

Ohm's Law was discovered by Georg Simon Ohm and is worth committing to memory:

E = I * R

or by manipulating the terms algebraically:

I = E / R

or

R = E / I

In this example:

I = E / R

I = 240 volts / 24 ohms = 10 amperes

A) 10 amperes
