According to Ohm's Law how is voltage related to resistance and current?

1). Voltage = (resistance) x (current)
2). Current = (voltage) / (resistance)
3). Resistance = (voltage) / (current)
I think #2 is Ohm's original statement, but any one of these can be massaged algebraically
in order to derive the other two.

What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What happens to voltage when resistance increases?
Ohm's law states that "The current is directly proportional to the applied EMF (voltage) and inversely proportional to the resistance in the circuit." <<>> if resistor exists, resistance decreases according to ohm's law, current is directly proportional to voltage and current is inversely proportional to resistance it means as current increases, voltage increases. resistance increases, current decreases so as voltage if there is no resistor, there should be no resistance except internal resistance of voltmeter and ammeter
Why current is directly proportional to voltage?
Ohm's Law: Current = Voltage times resistance, hence current is directly proportional to voltage.
What does voltage current mean?
V=IR, voltage is directly propostional to current and resistance (by ohm's law).CommentVoltage is not 'proportional to resistance'. Resistance is a constant, and is not affected by voltage at all.
Will current increase if the voltage in a circuit is increased?
Ohm's Law states Voltage = Current x Resistance. Hence if voltage is increased and resistance is constant, current will increase proportionally to the rise in voltage.
How are voltage resistance and current related?
Current, voltage and resistance are related by the Ohm's law formula which states that current is directly proportional to the applied voltage and inversely proportional to the resistance at a constant temperature. Stated mathematically: I = E/R where I = current in amperes, abbreviated to A E = voltage in volts, abbreviated to V R = resistance in ohms, usually signified by the Greek omega Ω
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?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
Is there a direct or inverse proportion between voltage and resistance?
voltage is directly proportional to resistance, and the current is inversely proportional to resistance. According to Ohm's Law, current is directly proportional to voltage.
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.
What is the relationship among voltage circuit and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
What is the relationship between the voltage and the current when the resistance is kept constant?
Ohm's Law: voltage = current * resistance. If resistance is a constant, then voltage is directly proportional to current.
How are current and voltage related are they directly proprtional or inversely proportional?
Current and Voltage are directly proportional. V=voltage, I=current, R=resistance V=I*R
What is the relation between voltage and current?
Voltage and current are two different things. Voltage is the electric potential difference between two points. Expressed in volts, it is also joules per coulomb. Current is the charge flow past a point. Expressed in amperes, it is also coulombs per second. You can relate voltage and current using Ohm's Law, which states that voltage is equal to current times resistance. Resistance is, therefore, equal to voltage divided by current. Using base units, resistance is equal to joules per coulomb divided by coulombs per second, which simplifies to joule-seconds per coulomb squared. That is a difficult unit to write, so we just use ohms as the unit.
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Does the current ina circuit increase with increase in temperature?
Resistance increases as temperature increases. If Voltage is held constant then according to Ohm's Law Voltage = Current x Resistance then current would decrease as resistance increases.
Does the voltage that runs through different appliances vary according to the resistance of the appliances?
No, it is the current (amperes) that vary according to the resistance.
