Current

Question 1

Charge Flow Definition and Formula

Answer 1

Charge is the Rate of Flow Of Current
Charge Flow = Current * Time

Q = I * t

Question 2

Potential Difference formula

Answer 2

Potential Difference = Current * Resistance

V = I * R

Question 3

How to Calculate Potential Difference in Series Circuit??

Answer 3

Potential Difference is Shared

Vtotal = V1+ V2+V3+…..

Question 4

How to calculate Current in Series Circuit??

Answer 4

Current is Same Everwhere

I1 = I2 = I3 ….

Question 5

How to Calculate the Resistance in Series Circuit??

Answer 5

Resistance Adds up

Rtotal = R1 + R2 + R3…….

Question 6

How to Calculate Potential Difference In Parallel Circuit??

Answer 6

Potential Difference is Same Across all Components

V1 = V2 = V3…..

Question 7

How to Calculate the Current in Parallel Circuit??

Answer 7

Current is Shared Between Branches

Itotal = I1 + I2 + I3….

Question 8

How to determine the amount of Resistance in Parallel Circuit??

Answer 8

Adding a Resistor to a Parallel Circuit Reduces the Total Resistance.

Question 9

How to Calculate Energy Transfer Using Power and Time??

Answer 9

Energy Transferred = Power * Time

E = P * t

Question 10

How to Calculate Energy Transfer Using Charge and Potential Difference??

Answer 10

Energy Transferred = Charge * Potential Difference

E = Q * V

Question 11

How to calculate Power using Potential Difference and Current??

Answer 11

Power = Potential Difference * Current

P = V * I

Question 12

How to calculate Power using Current and Resistance??

Answer 12

Power = Current^2 * Resistance

P =I^2 * R

Question 13

Transformers are 100% Efficient.

How to Calculate power in Input and Output Coil??

Answer 13

Power in Primary Coil = Power in Secondary Coil

V1 * I1 = V2 * I2
