When the potential difference across a lamp is 3.3V the current is 0.15 calculate the resistance of the lamp and give the unit

marissa [1.9K]

Answer:

22Ω

Explanation:

Given parameters:

Potential difference = 3.3V

Current = 0.15A

Unknown:

Resistance = ?

Solution:

According to ohm's law, potential difference, current and resistance are related by the expression below;

V = I R

where V is the voltage

I is the current

R is the resistance

3.3 = 0.15 x R

R = $\frac{3.3}{0.15}$ = 22Ω
