If you are looking for the resistance of each resistor in either a series circuit or a parallel circuit you must measure the current I and the voltage V for each resistor. Then calculate its resistance using Ohms Law R = V / I where I = current (Amps), V = voltage (Volts) and R= resistance (Ohms).
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
Voltage will be same in all branches. Voltage= Current * Total Resistance
The current flow in an electrical circuit depends on the applied electromotive force (EMF, measured in volts), and the total resistance along the entire circuit. Rising EMF or dropping resistance cause increased current flow
The current divides itself according to the resistance of each fork. If the resistance is equal, half the total current flows in each leg. The current flowing into the fork always equals the total current flowing into each of the legs.
Series circuit: The total voltage is the sum of the voltage on each component. The total resistance is equal to the sum of the resistance on each component. The total current is equal in every component.
ohms law calculation for a series circuit - Total Resistance = Total Voltage divided by Total Current
Current= Volage/Resistance
It depends upon the resistance values. Series resistance is the summation of all of the resistances, but to calculate the parallel is more complicated. Once the total resistance of each configuration is known, find the total current for each then multiply the current by the source voltage and this will provide the power.
You can't. You need to find the information about current -- a homework question normally gives you a hint.
Total resistance.
Current will be decreased because of the resistance of the ammeter added to the circuit's resistance. In other words total resistance increases.
The current will be zero if there is no voltage.
A: The EMF and total resistance
Resistance
Ohm's law is the basic answer. Voltage = Current * Resistance is ohms law. In order to find current divide voltage by Resistance V/R=I where I is current.
By Ohm's Law, resistance is voltage divided by current.
If the resistors are connected in series, the total resistance will be the sum of the resistances of each resistor, and the current flow will be the same thru all of them. if the resistors are connected in parallel, then the current thru each resistor would depend on the resistance of that resistor, the total resistance would be the inverse of the sum of the inverses of the resistance of each resistor. Total current would depend on the voltage and the total resistance
