Question

Since V=W/Q and I=Q/t
So Q=W/V and Q =i*t
Outing them together
W/V=I*t
Therefore I is Inversely proportional to V, as we know by ohms law v is directly proportional to I, Where thins above equation goes wrong and why this contradiction occurs?

Answer 1

it is a total different case where it formula for power

p =vi

and other is of resistance

v=ir.

Answer 2

Answer:

It's conventionally proportional to I....

Where v=ir.....

If you keep the power constant, then V=PI means that voltage is inversely proportional to current. However, because V=IR, we can write that P=I2R. Therefore, if we say resistance is constant, then power must change with current, which means that voltage is no longer inversely proportional to current.

Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.
