Question

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 1

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

`(v)/(i) = r`

`r = (125.6)/(7.9)`

`r = 15.8`

Answer 2

• Current=I=7.9A
• Voltage=V=125.6V

• Resistance=R

Apply ohms law

`\\ \tt\hookrightarrow (V)/(I)=R`

`\\ \tt\hookrightarrow R=(125.6)/(7.9)`

`\\ \tt\hookrightarrow R=15.8\Omega`
