If you know the current through one resistor in a DC circuit then do you know the current through all the other resistors?
No. Current and voltage are directly proportional to one-another and both are related to resistance by Ohm's law: V = IR or Volts = Current * Resistance So the current will depend upon the voltage and the circuit resistance by rearranging the above equations: I = V/R Meaning that the current will decrease as circuit resistance is increased if the voltage remains constant.
What would happen to circuit if there was no resistance?
a circuit with no resistance or zero resistance can be considered as open circuit in which the current is zero. without resistance the circuit just becomes open ()
Current in a circuit is inversely proportional to?
In a circuit , current is inversely proportional to the resistance.
Why might the current in a short circuit be higher than the current in the original circuit?
The current in a short circuit may be very high because the resistance in the short circuit is probably less than the resistance in the original circuit.
How could you calculate the resistance of a circuit?
A variety of techniques can be used. Node-Voltage and Mesh-current (or Loop-current) methods, for example. See related link for examples. If there is a single voltage source in the model, then find the current supplied, and Resistance = Voltage/Current. {R = V/I} You could simulate/ model the circuit on a computer then apply the power profile and a current value will be calculated. Or if you have the circuit working, Place an amp meter into the circuit and measure the current. V/i = resistance.
What is the electric force that makes current flow in a circuit is related to is?
The electric force that makes current flow in a circuit is related to the resistance.
How are current and resistance related in a circuit?
The current between any two points in the circuit is the voltage between those two points divided by the resistance between the same points.
The electric force that makes current flow in a circuit is related to the what?
The electric force that makes current flow in a circuit is related to the resistance.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
When resistance is in a circuit what happens to the current?
When you add resistance to a circuit, current goes down. Ohm's Law: current = voltage divided by resistance.
Why doesn't current decrease in series resistance circuit though resistance opposes current?
If you add another resistor or just increase the resistance the current will decrease. I think the statement you are talking about means that whatever the current is in the series circuit it will be the same everywhere in that circuit, on both sides of the resistance. The resistance lowers the current in the entire circuit, not just after the resistance.
What is a relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship among voltage current and resistance in a circuit?

In a circuit , current is inversely proportional to the resistance.
The amount of current in a circuit can what by increasing the amount of resistance present in the circuit?
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
