What is the relationship among voltage current and resistance in a circuit?
Voltage = (current) x (resistance) Current = (voltage)/(resistance) Resistance = (voltage)/(current)
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 algebraicallyin order to derive the other two.
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.
Why is there zero current when a lightbulb burns out?
because there is no voltage and resistance?
What is the relationship between lamp brightness and resistance in a series circuit?
The higher the resistance the dimmer the light will become. The voltage drop (current) is proportional to the resistance as seen in the equation V=IR, since voltage remains the same throughout a series circuit if the equivalent resistance goes up the amount of current reaching the lightbulb must go down to equal the voltage thus creating a dimmer lightbulb.

What voltage is required to sustain a current of 0.50 through a light bulb resistance of 190?
The voltage of a circuit with a resistance of 250 ohms and a current of 0.95 amps is 237.5 volts. Ohms's law: Voltage = Current times Resistance
If a circuit has a resistance of 4 ohm's how much voltage is needed to produce a 1.4 current in the circuit?
Voltage across a resistance = (resistance) x (current through the resistance) =4 x 1.4 = 5.6If the ' 1.4 ' is Amperes of current, then the required voltage is 5.6 volts.
How can you determine the resistance of a current?
Voltage = Current x Resistance giving us Current = Voltage / Resistance i.e. Voltage divided by resistance
Calculate the voltage required to produce a current of 2.0 A in a wire with a resistance of 16?
32v
Voltage muiltiplied by resistance measures to current?
No. Voltage divided by resistance is equal to current.
How do you compute for voltage if current and resistance is given?
Voltage = Current * Resistance (Ohm's law)
The voltage required to produce a current of 2.0A in a wire with a resistance of 16?
if current and resistance are know are known then voltage can be calculated using OHMS LAW V=I*R 2*16= 32 Volt
