PROBLEM:
A coffee cup immersion hitter utilizes a heating coil with a resistance of 9 ohms. Determine the current through the coil when operated at 230.
FORMULA:
[tex]I = \frac{V}{R} [/tex]
where:
I = is the current.
V = is the voltage.
R = is the resistance.
GIVEN:
Resistance = 9 ohms
Voltage = 230 volts
Current = ?
SOLUTION:
[tex]I = \frac{V}{R} \\ \\ I = \frac{230 \: volts}{9 \: ohms}[/tex]
[tex]I = 25.55[/tex] amperes
ANSWER:
The current is 25.55 amperes.
