Answer:
88 Watts
Explanation:
From the question given above, the following data were obtained:
Resistance (R) = 0.22 Ohm
Current (I) = 20 A
Power (P) =.?
P = IV....... (1)
From ohm's law,
V = IR ........ (2)
Substitute the value of V in equation (2) into equation (1)
P = IV
V = IR
P = I(IR)
P = I²R
With the above formula (i.e P = I²R), we can obtain the power lost to heat as follow:
Resistance (R) = 0.22 Ohm
Current (I) = 20 A
Power (P) =.?
P = I²R
P = 20² × 0.22
P = 400 × 0.22
P = 88 Watts
Thus, the power lost to heat is 88 Watts.
