FIGURE 25.
SOLVING FOR TOTAL POWER IN A SERIES CIRCUIT.
RT = 5 Ohms 4 10 Ohms + 15 Ohms
RT = 30 Ohms
By using the total resistance and the applied voltage, the circuit current
is calculated.
By means of
the
power formulas, the
power can
be
calculated
for
each
resistor:
For R1:
P1 = I2 X R1
P1 = (4 amps)2 x 5 Ohms
P1 = 80 watts
