What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
How do you find the value of resistance?
By Ohm's Law, resistance is voltage divided by current.
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 the resistance of an object if a voltage the voltage of 40 V produces a current of 5?
Ohm's Law: Resistance = Voltage divided by Current 40 volts divided by 5 amperes = 8 ohms.
What equation relates power to current and resistance?
Power = (current) times (voltage)Current = (Power) divided by (voltage)Voltage = (Power) divided by (current)
What are the mathamatical relationships in Ohm's Law in AC circuits?
Ohm's Law Voltage = Current x Resistance Current = Voltage divided by Resistance Resistance = Voltage divided by Current
Voltage muiltiplied by resistance measures to current?
No. Voltage divided by resistance is equal to current.
What is voltage divided by current?
resistance
How is the resistance of a resister calculated?
ohms law calculation for a series circuit - Total Resistance = Total Voltage divided by Total Current
What will happen in a circuit if the voltage does not change but the resistance in the circuit increases?
If the resistance increases, while the voltage stays the same, current will decrease. Current = voltage divided by resistance
How do you find the value of resistance?
By Ohm's Law, resistance is voltage divided by current.
What happens to the current in a device if the resistance of the device increases and the voltage difference stays the same?
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
What does power divided by speed equal?
Ohm so correctly said: Voltage divided by current equals resistance. Voltage divided by current will tell you the value of a circuit's resistance. But resistance is not affected by either voltage or current. It is determined by the length, cross-sectional area, and resistivity (type of conducting material) of the conductor. Resistivity is, in turn, affected by temperature. So voltage divided by current tells you what the resistance happens to be - changes in voltage or current do not affect resistance.
How is current related to resistance in a circuit?
Ohm's law: voltage is current times resistance. Restating this; current is voltage divided by resistance, so increasing resistance would decrease current.
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
How can calculate resistance for negative dc voltage?
Resistance calculations are the same no matter what the polarity of applied voltage. R=E/I Resistance (in ohms) = Voltage (in volts) divided by Current (in amperes)
Should you increase voltage or resistance to increase flow in a circuit?
To increase (current) flow in a circuit you increase voltage (or decrease resistance). Ohm's Law: Current = Voltage divided by resistance
