Question

What current flows through a hair dryer plugged into a 120-volt circuit if it has a resistance of 30

Answer 1

Answer:

current = 4 A

Step-by-step explanation:

here's the solution,

we know :-

$current = \frac{potential \: diffrence}{resistance}$

=》

$i = \frac{120}{30}$

( here, i represent current)

=》

$i = 4$

so, current flowing in the circuit = 4 amperes

Answer 2

Ircuit contains a 1.5 volt battery and a bulb with a resistance of 3 ohms. Calculate the current. I = V ÷ R = 1.5V ÷ 3Ω = 0.5A. 5. What current flows through a hair dryer plugged into a 120 Volt circuit
