Ash is working in the lab, and comes across a box of unlabeled resistors (thanks to his messy coworker who never puts them back properly).
He remembers that he can find out the resistance using an ammeter to measure current, and a battery with a known voltage.
Ash picks a resistor of unknown resistance (in Ω), connects it to some wires, and then plugs in a battery with a voltage of 29.7 V. This creates a circuit. Using the ammeter, he finds that the current in the circuit is 4.8 A.
In ohms, what is the resistance of the unknown resistor?
Answer: _____Ω.

In ohms, the resistance of the unknown resistor is 6.19 amps.

What is the ohm's law?

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Therefore in ohm's law, V = IR

V = voltage

I = current

R = resistance

To calculate the resistance, we have

R = V/I

where Voltage = 29.7

Current , I = 4.8

Resistance= 29.7/ 4.8 = 6.19 amps

In conclusion, Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
