High School How Do You Determine the Direction of Potential Change in a Resistor?
So when my book says the "voltage drop as we go from higher potential A to lower potential B across the resistor is equal to Current X Resistance" , it is actually talking about the magnitude of the change in potential? Not the actual change in potential as the words "voltage drop" seems to...- streetfightr4

High School Current in DC Circuits: Positive & Negative
sorry I am not very good at this but let's say I have a battery with + and - terminals and I put a wire between them. So now I am guessing the electrons flow from the - terminal to the + terminal through the wire. Now let's say I choose the the direction of the flow of the electrons as the...- streetfightr4

High School How Do You Determine the Direction of Potential Change in a Resistor?
cool that was very helpful but how can one talk about the magnitude of ChangeInPotential when current in the formula can be negative?- streetfightr4

High School Current in DC Circuits: Positive & Negative
lets say I have a direct current circuit and i have a battery with + and - terminals with a wire between them and i have electrons flowing from the negative terminal to the positive terminal through the wire. Is the current in this case a positive value or a negative value? and now let's say...- streetfightr4

High School How Do You Determine the Direction of Potential Change in a Resistor?
lets say my circuit is a direct circuit and I have a battery with plus and minus terminals connected to a load resistance. there are also wires between the load resistance and the battery terminals. And let's say 1) I go along the wire starting from the plus terminal all the way to the...- streetfightr4

High School How Do You Determine the Direction of Potential Change in a Resistor?
hi, in the formula ChangeInPotential = Current X Resistance (formula for change in potential across a resistor) , if the resistor has two ends (point A and point B), how do I know wether it is the change in potential from point A to point B or from point B to point A- streetfightr4
