Where V=stands for voltage, I=stands for current and R=stands for resistance. voltage=current multiplied by resistance so, by transposition, resistance=voltage divided by current. or R=V/I, R=9/3 The resistance is 3 ohms.
as by ohm's law, v=ir
r = v/i
therefore the resistance is 9/3=3 ohms

How do you Calculate the voltage of a battery if the resistance is 20hms and the current is 0.35 amperes?
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
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.
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.
450 amp-hour battery bank?
The rating of 450 amp-hours in a battery bank means that the battery can supply 450 amperes for one hour, so to speak. In reality, these ratings are normalized to an eight hour rate, which means that this battery can supply about 56 amperes for eight hours. Actual run time at 450 amperes would be somewhat less than an hour.
How do you Calculate the voltage of a battery if the resistance is 20hms and the current is 0.35 amperes?
Use Ohm's law. V = I * R where V is voltage in volts, I is current in amperes, and R is resistance in ohms.
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.

I have no idea
How many amps is a lawn mower battery?
The apmeres depend on the resistance of the circuit. The battery will be a certain voltage, and dividing the voltage by the resistance gives you amperes. V = I*R
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.
A circuit has total resistance of 5 ohms and a current of 0.3 amperes What voltage must the battery supply?
1.5 volts
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 do you calculate the resistance of a battery?
some batterys have a line on them which shows how much they have left
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 many ampere in a 12V battery?
The number of amperes is unrelated to the voltage. The maximum amount of current (in amperes) that you can take from the battery depends on the exact build of the battery.
What is the standard battery amperes for 1985 jaguar xj6?
12 V and 88 amperes
