Question

I need help know in the relationship with V=I*R

Answer 1

Current and Voltage
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

Not sure what your question is...

Answer 3

the relationship between both of them. like one increases and the other? decreases?

Answer 4

the relationship meaning the way they connect; depending on eachother and if they can increase or decrease / lighter or not etc;

Answer 5

for example the higher the resistance - the lower the current.

Answer 6

You already know that V = I*R and that tells you most of what you need to know.

For instance, if you hold V constant and increase R, I must decrease proportionally. If you hold V constant and decrease R, I will increase proportionally. Similarly, if R is constant and you increase V, I must increase proportionally. If you hold R constant and decrease V, I will also decrease proportionally.

Answer 7

These are simple mathematical relationships

Answer 8

You had quite a list. With regard to the last two items. Lets look at the "Number of batteries and amount of voltage" Well it depends on manner of battery configuration. If they are connected in series in a plus to minus such as shown here The voltages add if they are in series where plus is connected to plus they are series opposing and the voltage would be as shown If the batteries are connected in a parallel configuration such as: The voltage is the same as for each battery.
