Question
A $10.0-\Omega$ electric heater operates on a $110-\mathrm{V}$ line. Compute the rate at which it develops thermal energy in $\mathrm{W}$ and in $\mathrm{cal} / \mathrm{s} .$
Step 1
We can use the formula: Power (P) = Voltage (V) × Current (I) But we don't have the current. So, we can use Ohm's Law to find the current: Voltage (V) = Current (I) × Resistance (R) Rearranging for current: Current (I) = Voltage (V) / Resistance (R) Now, we Show more…
