What is the difference between a conductor and an insulator?

A conductor allows current to flow easily through it. Insulators don't allow current to flow through it.

Draw a series circuit with two resistors R1 and R2 with voltages V1= 5V, v2=10v. Ammeter in the circuit shows a current 0.05A passing through the circuit.


 R1=5v,R2=10v

I=0.05A

What is the voltage drop across R2

9v

How does the power change when voltage increase

It increases

How to Identify a Conductor if provided with a series circuit and an ammeter

for conductors Place the material in the series circuit so that it completes the circuit path.If the material is a conductor, the ammeter will register a significant current flowing through it. Conductors allow electricity to flow freely, so the current will be measurable.

what is the current flowing through resistor 2 if Vt=6 and R1=1 ohms R2=3 ohms R3=2 ohms

2 Amps

What will be the power of the car battery of 10V if it provides 0.5A current

10 times 0.5 = 5 w

How to identify an insulator if provided with a series circuit and ammeter?

for Insulators Place the material in the series circuit so that it completes the circuit path.If the material is an insulator, the ammeter will register little to no current flowing through it. Insulators do not allow electricity to flow, so the current will be negligible or zero.

What is the resistance of R1

100 Ohm

What happens to the remaining bulbs in a circuit when one bulb goes out? (Series verses parallel)

The whole circuit turns off or stops working

How does Fuses and circuit breakers work?


           A.  Fuses and circuit breakers help to discharge the excess electricity in the circuit

 B. Fuses and circuit breakers are designed to protect people from shocks.

C. None of these is correct.

D. Fuses and circuit breaker protect machinery and electrical systems by turn the circuit off when too much current pass through it.
