When 2 resistors are connected in parallel r1r2 are?
Two resistors connected in parallel are 1/2 the sum of their resistance. The resistance of two resistors connected in series is the sum of their resistance. For example: The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in parallel is 100+200 divided by 2 = 150 ohms. The total resistance of a 100 ohm resistor connected to a 200 ohm resistor in series 100+200= 300 ohms.
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.
When a 1 ohm resistor and a 1 ohm resistor are connected in series what is their conbined resistance?
The combined resistance will be 2 Ohms.
Does a Resistor have a different resistance when connected to a power source vs if the resistance is tested when the resistor is out of circuit?
No, the resistance of a resistor remains the same whether it is connected to a power source or tested out of circuit. The resistance value is an intrinsic property of the resistor and does not change based on the external conditions.
What is the equivalent resistance of three resistor with 3 ohms connected in star?
There is no 'equivalent resistance' for three resistors connected in star.
Can you calculate the resistance of a component using a meter and a resistor?
yes you can! you can use a multimeter and a resistor.
If a 15-ohm resistor is connected in parallel with a 30 ohm-resistor the equivalent resistance is?
Rt = 10
What resistance must be connected in parallel to 6.0-ohm resistor to reduce the combined resistance to 15-ohm?
No such resistor exists. Any resistor placed in parallel with a 6.0 ohm resistor is going to reduce the combined resistance below 6.0 ohms.
What will happen to the other resistor if the number of resistor decreases?
the voltage across that resistor will increase if it is in series with the other resistors. the current through that resistor will increase if it is in parallel with the other resistors.
How much amount of heat will produce in 22kilo ohm resistor?
If the resistor is conducting electrical current, then the power it dissipates (heat energy per second) is(current through it)2 times (22,000)or(voltage across it)2 divided by (22,000).If the resistor is connected in an unpowered circuit, or stored in a drawer, then it dissipates zero heat.
A 120 resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source what is the current running though the 40 ohm resistor?
To calculate the total current in the circuit, you first need to find the total resistance by using the formula for resistors in parallel: 1/Total Resistance = 1/120 + 1/60 + 1/40. Once you have the total resistance, you can use Ohm's Law: Current = Voltage / Total Resistance. Finally, to find the current running through the 40 ohm resistor, you divide the total current by the resistance of the 40 ohm resistor.
What is the net resistance of two resistor connected in series?
The net resistance of two resistors connected in series is the sum of the two resistances. RSERIES = Summation1toN RN
