A wire with resistance R is connected to the terminals of a 30 V battery. What is the current through the wire if the wire has the resistance?
Your current will be 30/R Amps. Where R is the resistance in Ohms.
On what factors the current flowing through a device depends?
Current flowing through a device depends on resistance offered by that device.
Does the resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
What is the current running through a 90 volt circuit?
It depends on the resistance of everything connected between the terminals of the power supply. If the resistance is infinite or very high, there is little or no current. As the resistance becomes less, the current becomes greater. In general, the current through a circuit with 90 volts applied to it is [ 90 / R ], where 'R' is the resistance of everything across the 90-volt power supply.
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.
What is meant by resistance of a current?
The resistance of a current is a measure of how difficult it is to push the electrons along.AnswerThere is no such thing as the 'resistance of a current'. Resistance is a characteristic of the material through which a current flows, not of the current itself.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
How will you describe the graph of resistance against current?
If resistance is high that time the current flow is low. Bcoz current always flow through the low resistance path.
What does a current flowing through a material meet with?
Resistance
What is a measure of how easily current will pass through a material?
resistance conductance or 1/resistance
Why shunt resistance is used ammeter?
A shunt resistance is a low resistance connected parallel to the galvanometer so that a large portion of current passes through the low resistance and a small fraction of current passes through the galvanometer this saves the galvanometer from damage
Which property makes it difficult for current to pass through?
Resistance in the circuit makes it difficult for current to pass through.
Would it be true to say that current causes voltage?
Volts = Current x Resistance. The voltage is where the potential resides for the amount of current flowing through a resistance. Think about the voltage as a potential source of electrons that then flow through a circuit depending on the Load, or resistance in this example.
What is the meaning of electrical resistance?
Definition Of Resistance In Electrical:Property of a material to oppose the flow of electric current through it is called Resistance.
A wire with resistance R is connected to the terminals of a 30 V battery. What is the current through the wire if the wire has the resistance?
Your current will be 30/R Amps. Where R is the resistance in Ohms.
Is the current pass through parallel short resistance?
no.because current always try to flow trough low resistance path.as short circuit has low resistance current pass trough short circuit
On what factors the current flowing through a device depends?
Current flowing through a device depends on resistance offered by that device.
