What unit is used to measure resistance
A string of 15 Christmas tree lights is connected in series to a 90 volt power source What is the value of the resistance of each light if the current flowing through the circuit is 2 amps
Three 15 ohm resistors are connected in parallel to a 30 volt battery What is the equivalent resistance through the circuit
What is the incoming voltage from the current source to the transformer called
the incoming voltage from the current source to the transformer
is called primary voltage.....
A string of 20 Christmas tree lights are connected in series to a 20 volt power source The bulbs each have a resistance of .5 ohm How much current is flowing through the circuit
Five resistors are connected together in series One resistor is 2 ohms one is 3 ohms one is 4 ohms one is 5 ohms and the fifth is 6 ohms What is the total resistance
Purely additive. 2+3+4+5+6=20.
A 5 ohm resistor a 20 ohm resistor and a 25 ohm resistor are all connected in series to a 100 volt power source What is the current running through the circuit
2 amps. 100 volts divided by 50 ohms = 2 amps. E/R=I.
What is the total current flowing through a 45 ohm resistor 1.4 amps and 20 ohm resistor 1.8 amps
Just add the amps (3.2 amps).
