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.

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

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

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.

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

5 ohms...

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

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

True

Choose true or falseIf all the resistors in a parallel sub-circuit have the same value the total current can be found by multiplying the current by the number of resistors

False.

What is the current running through resistor one

Three

What is the voltage drop running through the parallel potion of the circuit

A: There is no voltage drop running through in a parallel circuit but rather the voltage drop across each branch of a parallel circuit is the same

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).

What is the voltage drop running through resistor one

What is the voltage drop running through resistor one
