Question

While cooking dinner, Dinah's oven uses a 125.6 V line and draws 7.9 A of current

Answer 1

• Current=I=7.9A
• Voltage=V=125.6V

• Resistance=R

Apply ohms law

$\\ \tt\hookrightarrow \dfrac{V}{I}=R$

$\\ \tt\hookrightarrow R=\dfrac{125.6}{7.9}$

$\\ \tt\hookrightarrow R=15.8\Omega$

Answer 2

While cooking dinner, Dinah's oven uses a 125.6 V line and draws 7.9 A of current when heated to its maximum temperature. What is the resistance of the oven when it's fully heated?

✒️ Answer:

===================

• Current=I=7.9A
• Voltage=V=125.6V

• Resistance=R

Apply ohms law

$\frac{v}{i} = r$

$r = \frac{125.6}{7.9}$

$r = 15.8$
