A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
Normally a high current flows through a short circuit even if there is no change to the voltage. Why is this?
A high current flows through a short circuit even if there is no voltage change because the resistance across the short circuit is zero.
How does electric resistance relate to energy transformation?
Power in a circuit is inversely proportional to the resistance, all other things being equal. Voltage equals amperes time resistances, so amperes equals voltage divided by resistance. Watts equals voltage times amperes, so watts equals voltage squared divided by resistance.
How many hertz in direct current?
Direct current has no frequency, it has voltage. also it has current that is measured in Amperes which is dependable of the resistance of the circuit. Alternating current has frequency because the electricity flows alternatively on both directions. If the frequency of AC is 50hz/s it means that the electricity flows forwards and backwards 50 times per second.
How many amperes 1.5kw are?
That depends on the voltage which the current flows through. I = P / U I = 1500 / U Where I is the current in Amperes and U is the effective voltage in Volts. (P is the power)
What are the three electrical guantities?
The three electrical quantities are current voltage and resistance. Current is measured in amperes (A) and is the rate at which electricity flows through a conductor. Voltage is measured in volts (V) and is the electrical force pushing the current through the conductor. Resistance is measured in ohms () and is the opposition to the flow of current. Current - measured in amperes (A) Voltage - measured in volts (V) Resistance - measured in ohms ()
What is the differnece between volts and amperes?
Voltage is power Amperage is current. you can have voltage but nothing runs without a closed circuit and then current flows.
How many watts are consumed by 1.25 amperes?
The number of watts produced by a current of 1.25 amperes can only be known if you also know either the applied voltage which caused that current to flow (W=I x E); or if you know the resistance through which the current flows. (W= I2 R).
How much current flows through a circuit if 2 coulombs of charge flows each second?
Current in amperes is coulombs per second, so 2 coulombs per second is 2 amperes.
What is the current that flows through an unloaded voltage divider?
The Bleeder current.
Does current flows through fruits?
If the voltage is great enough a current will flow.
Is current is drop when it flowing through the resistor?
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
Does voltage flow across or through a resistor?
No. If a voltage is applied across a resistor, a current flows through it.
A resistance of 10 ohms is placed across a 9 volt battery what current flows through the battery?
No current flows through the battery. There is a current through the external circuit. I = E/R = 9/10 = 0.9 amperes.
How much current flows through a resistor with zero potential difference?
No current flows when the the voltage is zero.
Why infinite current flows when voltage applied is zero?
No current flows when the applied voltage is zero.
