 What is the maximum resistance which can be made using five resistors each of 1/5⦠?
Ā
The resistors in parallel in the following circuit are: -

Ā The resistivity does not change if
Assertion: To measure the current in a circuit, an ammeter is always connected in series.
Ā Ā Ā Ā Ā Reason: Ammeter offers very high resistance to the circuit in which it is connected.
Assertion : Fuse wire must have high resistance and low melting point.
Reason Ā :Ā Ā Fuse is used for small current flow only.
State Ohms law
What is meant by saying that a potential difference between two points is 1V?
100 joules of heat is produced per second in a 4 ⦠resistor. What is the potential difference across the resistor?
a)Ā Ā Ā Ā Ā Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?
State Joules law of heating
