When an AC circuit contains both resistance and inductance the current and voltage will be in phase. This means having waveforms that are of the same frequency and that pass through corresponding value.

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.
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.
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.
It doesn't. the impedance of the inductor will, following the rule j*w*l, where l is inductance, w is frequency in radians and j is the imaginary number designating this a reactance, not resistance.
Commonly the answer for which of the following statements is true concerning the outline and matrix formats used when creating a format task organization is none of the above.
