The current power in the circuit section is calculated by the formula:
P = U * I, where U is the voltage in the network (U = 127 V), I is the current strength.
According to Ohm’s law: I = U / R.
Then:
P = U * I = U * U / R.
Let’s calculate the current power in the circuit section:
P = U * U / R = 100 * 100/200 = 50 W.
Answer: The current power in the circuit section is 50 watts.
