If resistor X has the same length and is made of the same material as resistor Y but has twice the diameter. Resistor X has the blank resistance of resistor Y?

R = r*L/A where: R = resistance r = material resistivity L = length A = area Since you are doubling the diameter, you are increasing the area by a factor of 4, so Y will have 1/4 the resistance of X.


At what level will typical resistors burn out?

A typical resistor will burn out when it dissipates power in excess of double its power dissipation rating for an extended period of time. The power dissipated by a resistor is equal to I2R or E2/R, where E = the voltage across the resistor I = the current through the resistor R = the resistance of the resistor


If the voltage dropped across a resistor increases by a factor of 10 the power dissipated by the resistor is?

The power dissipated by a resistor is given by the formula ( P = \frac{V^2}{R} ), where ( V ) is the voltage across the resistor and ( R ) is its resistance. If the voltage increases by a factor of 10, the new power can be expressed as ( P' = \frac{(10V)^2}{R} = \frac{100V^2}{R} = 100P ). Therefore, the power dissipated by the resistor increases by a factor of 100.


What resistor is need pull 1500Ma?

To calculate the resistor needed to pull 1500 mA (1.5 A), you need to know the voltage across the resistor. Using Ohm's Law (V = I × R), you can rearrange it to find R (Resistance = Voltage / Current). For example, if the voltage is 5V, the resistor needed would be R = 5V / 1.5A = 3.33 ohms. However, ensure the resistor can handle the power dissipation, calculated as P = I² × R, which in this case would be approximately 7.5 watts.


When will the resistance of a resistor be numerically equal to its resistivity?

The resistance of a resistor will be numerically equal to its resistivity when the resistor's dimensions (length and cross-sectional area) are such that the resistance ( R ) is calculated using the formula ( R = \frac{\rho L}{A} ) and the units align accordingly. Specifically, this occurs when the length ( L ) of the resistor is equal to its cross-sectional area ( A ). In such a case, ( R ) would equal ( \rho ) if they are expressed in compatible units.

How Determine the power dissipated by the resistor?

Power dissipated by the resistor = I^2 * R or V^2 / R, where R = its resistance value, I = the current in the resistor, and V = the voltage drop across the two terminals of the resistor. You need to measure or find the information of either I (using an ammeter) or V (a voltmeter).
