Use Ohm's law.
V = I * R
where V is voltage in volts, I is current in amperes, and R is resistance in ohms.

What is the resistance in a discman if it is connected to an 8.6V battery and draws a current of 0.9 Amperes?
I have no idea
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
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.
What is the value of amperes for 100 volts at constant resistance?
V = I*R, so take 100 volts and divide it by the value of the resistance to get the current. Current is measured in amperes.
How many amps will you get on a 9 volt battery with a 100 ohm resistor and a 100 ohm resistor and a 470 ohm resistor?
You need to calculate the equivalent resistance. For instance, if the three resistors are connected in series, simply add all the resistance values up. Then, you calculate the current (in amperes) using Ohm's Law (V=IR); that is, you need to divide the voltage by the resistance.
Calculate the voltage of a battery if the resistance is 80 ohms and the current is 0.5 amp?
Ohm's law: Voltage is resistance times current. 80 ohms time 0.5 amperes = 40 volts.
What is the resistance in a discman if it is connected to an 8.6V battery and draws a current of 0.9 Amperes?

Calculate the current taken by a 100 watts lamp having a working resistance of 200?
0.02 amperes
Calculate the current if voltage equals 19.8 V and resistance equals 2.2 ohms?
9 amperes.
What is measured in amperes a current voltage or an Resistance?
Electrical current is measured in amperes.
What is the voltage of microwave with a resistance of 5 ohms and current flowing of 10 amperes?
It looks as if you can use Ohm's Law to calculate this: V=IR (voltage = current x resistance).
A circuit has total resistance of 5 ohms and a current of 0.3 amperes What voltage must the battery supply?
1.5 volts
In a circuit with a 6 V battery hooked up to a 3 Ohm light bulb what does the current measure?
2 amperes (current = voltage/resistance)
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 and circuit that includes a 9- volt battery and a bulb with a resistance of 3 ohms?
A resistance of 3 ohms connected between the terminals of a 9-volt battery will result in a current of 3 Amperes. If the battery is one of those little ones with snaps on top, it may be able to produce 3 amperes of current for about 3 seconds before it rolls over and totally dies.
How can calculate resistance for negative dc voltage?
Resistance calculations are the same no matter what the polarity of applied voltage. R=E/I Resistance (in ohms) = Voltage (in volts) divided by Current (in amperes)
The current in an electrical conductor varies inversely as the resistance of the conductor The current is 2 amperes when the resistance is 960 ohms What is the current when the resistance is?
