Math Problem Statement
An electrical circuit has four electrical loads in series. These loads measure 4.00 volts, 3.25 volts, 6.50 volts, and 7.75 volts. Calculate the source voltage.
An electrical circuit has a power source voltage of 14.5 volts. Within the series circuit, there are two electrical loads. The first load measures 9.6 volts. Calculate the voltage of the second load in the circuit.
496 technician is is gnosing an electrical circuit issue. The source voltage is 126 volts. There is only one electrical load built into the circuit, and it has a voltage drop of 11.4 volts. This voltage drop test indicates unwanted resistance in the circuit. Calculate the voltage drop caused by the unwanted resistance in the circuit.
A technician is using a multimeter to make electrical measurements. The resistance of a headlight circuit is 3.5 O and the amperage measures 4.05 amps. Calculate the voltage of this circuit.
A technician is using a multimeter to make electrical measurements. The resistance of a horn circuit is 2.15 & and the amperage measures 5.8 amps. Calculate the voltage of this circuit.
Solve these with this formula source voltage = voltage drop, + voltage drop, + voltage drop and take this example formula too for other problems which ever is needed 20 volts = 12 volts + x volts 20 volts - 12 volts = x volts 8 volts = x volts
