What unit is used to measure resistance

ohm

A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor

It would be about 4 amps.

What is the drawing of an electrical circuit called

"schematic diagram" or "schematic drawing"

What is the process of creating electricity in one place and moving it to another for use

Transmission lines.

How current passes through resistor.
  • What is the current running through resistor four?1 amps..!
  • What is the current running through resistor one? 3 amps...!
  • What is the current running through resistor three? 2amps..!
  • What is the current running through resistor five? 3 amps..!
  • What is the voltage drop running through resistor five? 45 volts...!
  • What is the equivalent resistance through the parallel portion of the circuit? 6 ohms

Answer

A resistor is a conductor, albeit one with a higher resistance than a length of wire, so current passes through it without any problem. The magnitude of the current will, of course, be somewhat lower because of the additional resistance.

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.

The total current that flows through a circuit is the same as the current that flows through each individual resistor connected in series

True

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).
