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 much voltage is required to make 2 amperes flow through resistance of 8 ohms?
Ohm's Law: voltage is current times resistance, so 8 amps times 2 ohms is 16 volts.
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.
Why you use mega ohm resistance in small electronics circuits?
Each resistor in a circuit performs a well defined function and its resistance is calculated by the circuit designer as the voltage across it divided by the current through it. Sometimes the value of resistance required is over 1,000,000 hms.
On what factors the current flowing through a device depends?
Current flowing through a device depends on resistance offered by that device.
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 voltage required to send a current of 4 amps through a resistance of 60ohm?
16 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.
Is One volt is the pressure required to force one amp of current through a circuit that has 1 Ohm of resistance?
yes
Calculate the voltage of required to push eleven amperes through a 20-ohm resistance?
U = RxI so 11x20=220 volts
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 is a measure of how easily current will pass through a material?
resistance conductance or 1/resistance
What does a current flowing through a material meet with?
Resistance
How is resistance related to electric currents?
Resistance affects how much current can flow; a higher resistance means either less current, or more voltage required for the same current. They are related in formula by V = IR, i.e. the product of resistance and current is the voltage across that component. Knowing any two allows you to work out the third.

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
A kettle is connected to a 120v outlet with a resistance of 9.6 ohms what is the current required to operate the kettle?
The formula you are looking for is V = IR where V = Voltage I = Current R = Resistance With some formula manipulation and numbers plugged in you get I = 120V / 9.6Ω I = 12.5A The kettle would have 12.5 volts of current running through it.
Which property makes it difficult for current to pass through?
Resistance in the circuit makes it difficult for current to pass through.
