For example, if your LED has a voltage of 3.6 and a current of 20 milliamperes, it will use 72 milliwatts of power.How do you calculate the power dissipation of a diode?Maximum total dissipation = PD, the amount of power (in watts) allowable for the diode to dissipate, given the ...
The current in a 47 \Omega resistor is 0.11 A. This resistor is in series with a 28 \Omega resistor and the series combination is connected across a battery. What is the battery voltage?The current in a 62-Omega resistor i...
To calculate the voltage amplitude across the resistor, use the basic formula V=IR. Answer and Explanation:1 Suppose, resistance in the circuit isR=250Ω, and the current in the circuit isI=0.10A. The expression to calculate...
In series combination of resistors, the current passing through each resistor is the same, while voltage across each resistor is different. The equivalent resistance in the series combination of resistors is given by; {eq}R_{eq}= R_1 + ...
Look for Voltage & Current Power (Watt) This is amount of power consumed by your laptop adapter and is it is measure in Watts (W). You do not need to match this value as it will come out the same as with your original power adapter, if you have correctly matched the output voltage...
next month, come from an alliance with Primarian, a Tempe, Ariz., startup founded by Intel veterans. They project that Pentium cores will soon be in the 0.5- to 0.8-volt range, with current spikes approaching 150 amps and overall power consumption in the range of 80 to 140 watts. ...
Cast metallic frame which contains a spongy lead active material. Reserve Capacity Rating (RC) – Number of minutes that a new, fully charged will deliver 25 amperes at 26.7°C/80°F and maintain a terminal voltage equal to, or higher than, 1.75 volts per cell. This rating represents the...
Additionally, given a series of resistors, either voltage or current can be determined using Ohm's law: V=IR where R is the total resistance of resistors in the circuit. Answer and Explanation: Before we get to calculating the ...
