Question

An alarm clock has a current of 4.5 amps and a resistance of 3.2 ohms. What is the voltage in the circuit?

Answer 1

R- 3.2 ohms i -4.5 amps v-? V-IR 4.5*3.2
Answer: 14.4 volts

Answer 2

14.4 V

Step-by-step explanation:

The problem can be solved by using Ohm's law, which states that:

`V=RI`

where

V is the voltage in the circuit

R is the resistance of the clock

I is the current in the circuit

In this problem, we have:

`I = 4.5 A` is the current

`R=3.2 \Omega` is the resistance

Substituting the numbers into the equation, we find the voltage:

`V=(4.5 A)(3.2 \Omega)=14.4 V`
