What unit is used to measure resistance

ohm

A transformer has 150 turns on the primary coil and is connected to a 120 volt power source How many turns will be needed on the secondary coil to provide a secondary voltage of 40 volts

fifty turns

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

The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the what effect

Doppler effect.

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

A pulley system is used to lift a 2000 newton engine up a distance of 3 meters The operator must apply a force of 250 newtons to the chain of the pulley system to lift the motor To lift the engine fi

250 newtons

A+ Answers

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).
