Solution: (2) A = [x : x is a multiple of 3] A = {3, 6, 9 ….} B = [x : x is a multiple of 5] B = {5, 10, 15 ….} A - (A ⋂ B) = (A ⋂... View Article
The internal resistance of an ideal ammeter will be zero since it should allow current to pass through it. The ammeter is connected in series in... View Article
The galvanometer coil has a small resistance about 100 ohms. The galvanometer is used to detect small electric current in the circuit. When there... View Article
Motion means the change in the position of the object over time. The motion can be mathematically described in terms of distance, displacement,... View Article
Acceleration is the rate of change of velocity. It is represented as a= ∆v/∆t ∆v is the change in velocity ∆t is the change in time... View Article
Entropy is related to the second law of thermodynamics. Entropy is a measure of the disorder of the system. If a small amount of heat dQ is given... View Article
According to Ohm’s law, the voltage or the potential difference between two points in a circuit is directly proportional to the current and... View Article
Ideally a voltmeter should have infinite resistance but in practice the voltmeter has a resistance in mega ohm or even higher. The voltmeter... View Article
