Question

which is the correct relationship between current , voltage and power ?

a decrease in power will occur if current is decreased and voltage remains the same

an increase in voltage with no change in current will result in an increase in power

in order to increase power there must be a decrease in either current voltage

the only way to decrease current is to decrease power

Answer 1

please help i think its b

Answer 2

yes this can be a relationship when we are taking about KVA or VA powers.

Answer 3

P = V * I OR:

1. IF V = K(constant) --> I = P/K ;
2. IF I = C (constant) --> V = P/C

Answer 4

so its c

Answer 5

well if you have a transformer ( alternating current). you have, P = no varies

Answer 6

so I would say D. I hope someone confirm that fact . .
