Question

What is relationship between:
Current and voltage

Answer 1

Resistance and Voltage
Light bulb brightness
Number of resistors and amount of voltage
Number of resistors and amount of current
Number of batteries and amount of voltage
Number of batteries and amount of current

Answer 2

Resistance and Voltage/Current and Voltage can both be described using Ohm's Law, or \[V=IR\]
Where V is voltage, I is current, and R is resistance.
To answer your first question, what is the relationship between current and voltage, lets use Ohm's Law, but keep R constant.
We can see that if we increase V(oltage), then the I, or current will have to increase too , because we kept R constant. This can be summed up by saying "Electric current is directly proportional to the voltage"
Try this approach (using Ohm's law, or V=IR) to answer your second question, the relationship between resistance and voltage.

Answer 4

V=IR

Answer 5

V=IR . It is given by ohms law.(at constant temperature)
Power P=IV .
So I=V/R
I=P/V
