When electric current is following in a curcuit if the voltage applied to the curcuit is increased the resistance will decrease true or false?
true
What is the resistance of a fuse bulb?
A lamp has two resistances: a 'hot' resistance (its operating resistance) and its 'cold' resistance (its resistance when switched off), and the hot resistance is significantly higher than its cold resistance.You can calculate its 'hot' resistance from its rated power and its rated voltage (assuming that it is being supplied at its rated voltage), by manipulating the following equation, to make Rthe subject: P= V2/RYou will, though, have to measure its cold resistance.
What is the relationship between total resistance and the resistance across each load?
There is no such thing as 'resistance across' a load! The correct term is 'resistance of a load'.To answer your question, it depends on how the loads are connected. If they are connected in series, for example, the total resistance is equal to the sum of the individual resistances. If they are connected in parallel, then you must use the following equation: 1/R = 1/R1 + 1/R2 + 1/R3 + etc.For any other connection, you will have to work it out individually.
Why does power decrease when resistance increases?
First, this statement stands as long as voltage is constant. If you held the current constant then power would increase as resistance increases.V=IR. For a fixed voltage if you increase the resistance (R) then the current (I) will decrease - following the formula.Power = VI so as the resistance increases the value of VI (power) decreases as V is constant and I gets smaller.Therefore the power is decreasing as the resistance increases (when voltage is held constant).Hope this helps.
Which of the following condition exist in a circuit of pure resistance?
in a circuit of pure Resistance (r), IE. voltage source (12 v DC battery) and pure resistance (a light bulb). the voltage (v) and current (i) will be in phase. by adding capacitors and/or inductors to the circuit V and I will be pulled out of phase.
