Question 1

Difference between Current and Static Electricity:

Answer 1

Current electricity is the flow of electrons through a conductor.

Static electricity is the build-up of electric charge on the surface of an object, not flowing.

Question 2

Current, Voltage, and Resistance:

Answer 2

In Series:

Current: Same everywhere

Voltage: Splits across components

Resistance: Adds up

In Parallel:

Current: Splits between branches

Voltage: Same across all branches

Resistance: Total resistance decreases

Question 3

Factors that Affect Resistance:

Answer 3

Material

Length of wire

Thickness (cross-sectional area)

Temperature

Question 4

Ohm’s Law:

Answer 4

V=I×R
(Voltage = Current × Resistance)

Question 5

Solving Circuits:

Answer 5

Use Ohm’s law
Simplify series/parallel resistors
Series: Rtotal = R1 + R2 +
Parallel:1 over Rtotal = 1 over R1 + 1 over R2
Solve step-by-step: find total resistance, then current, then voltage across each part
