What unit is used to measure resistance

ohm

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

3
3 ohms

Three 15 ohm resistors are connected in parallel to a 30 volt battery What is the equivalent resistance through the circuit

5 ohms...

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

2 amps. If it is D.C.

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).
