What else can I help you with?
What is the current through a 40-ohm resistance that has a potential difference of 160 volts?
lll
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
Does potential difference change with change in resistance?
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
What is the value of amperes for 100 volts at constant resistance?
V = I*R, so take 100 volts and divide it by the value of the resistance to get the current. Current is measured in amperes.
What is the current through a 40-ohm resistance that has a potential difference of 160 volts?

What is the ratio of potential difference to the current of a circuit?
The ratio of potential difference to current in a circuit is known as resistance, measured in ohms (Ω). This relationship is described by Ohm's Law, which states that resistance equals voltage divided by current (R = V/I).
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
What is the ratio of electric current and voltage in the closed circuit?
The name given by engineers to the ratio of "electrical potential difference" (expressed in volts) to "rate of current flow" (expressed in amperes) is "resistance" (expressed in ohms).
What is 1000 ohms?
"1,000 ohms" is the resistance of anything through which the current, expressed in amperes, is numerically equal to 0.001 times the potential difference between its terminals, expressed in volts.
Current is proportional to the potential difference and inversely proportional to its?
Current is proportional to the potential difference and inversely proportional to resistance. Ohm's law: Current equals voltage divided by resistance
Does potential difference change with change in resistance?
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
Is potential difference measured in volts or amperes?
Volts; The Ampere is the unit for current in charge per second.
How is electrical resistance calculated?
Resistance (Ohms) = Potential Difference (Voltage) / Current (Amps)
How many amperes of current will flow in a circuit if the voltage difference is 9 V and the resistance in the circuit is 3 Ω?
Ohm's Law: Current = Voltage divided by resistance 9 volts divided by 3 ohms = 3 amperes.
How does resistance after current?
Assuming you are asking "How does resistance altercurrent?", then the answer is that, for a given value of potential difference, the current is inversely-proportional to the resistance. E.g. doubling the resistance will reduce the current by half.
