Chapter 7 - Electrical Circuits

Question 1

Ohm’s Law

Answer 1

Potential difference across a conductor directly proportional to current through conductor provided temp. remains constant.

Question 2

Ohm

Answer 2

A conductor ( /resistor ) provides a resistance of 1 ohm when a current of 1 amp flows through it and a potential difference across it’s ends is 1 Volt.

Question 3

Electrical Power

Answer 3

Rate at which electrical energy is converted into other form of energy in an electrical circuit.

Question 4

Potential Difference

Answer 4

Work done per unit. Positive charge.

Question 5

Current

Answer 5

Rate of flow of charge.

Question 6

EMF

Answer 6

Total energy supplied per coulomb of charge by the cell.
