When the car engine is started, the starter winding with an electrical resistance of 0.6 Ohm is connected to the poles of the 12 V battery. What is the current in the circuit equal to?
U = 12V.
R = 0.6 ohm.
I -?
The strength of the current I in the starter winding is determined by Ohm’s law for the section of the circuit: I = U / R, where U is the voltage at the battery terminals, R is the resistance of the starter.
I = 12V / 0.6 Ohm = 20 A.
Answer: the current in the starter winding is I = 20 A.
