Power Drop in Brush DC Generator Solution

STEP 0: Pre-Calculation Summary
Formula Used
Brush Power Drop = Armature Current*Brush Voltage Drop
PBD = Ia*VBD
This formula uses 3 Variables
Variables Used
Brush Power Drop - (Measured in Watt) - Brush Power Drop refers to the power that is lost due to the voltage developed across the brushes and the commutator as the electrical current passes through them.
Armature Current - (Measured in Ampere) - Armature Current is defined as the current developed in the armature of an electrical DC generator due to movement of rotor.
Brush Voltage Drop - (Measured in Volt) - Brush Voltage Drop refers to the voltage that is lost across the brushes and the commutator as the electrical current passes through them.
STEP 1: Convert Input(s) to Base Unit
Armature Current: 0.75 Ampere --> 0.75 Ampere No Conversion Required
Brush Voltage Drop: 5.85 Volt --> 5.85 Volt No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
PBD = Ia*VBD --> 0.75*5.85
Evaluating ... ...
PBD = 4.3875
STEP 3: Convert Result to Output's Unit
4.3875 Watt --> No Conversion Required
FINAL ANSWER
4.3875 Watt <-- Brush Power Drop

Power Drop in Brush DC Generator Formula

Brush Power Drop = Armature Current*Brush Voltage Drop
PBD = Ia*VBD

What is Brush Drop?

The brush drop depends upon the brush contact voltage drop and the armature current Ia. The voltage drop occurring over a large range of armature currents, across a set of brushes is approximately constant. If the value of the brush voltage drop is not given then it is usually assumed to be about 2 volts.

How to Calculate Power Drop in Brush DC Generator?

Power Drop in Brush DC Generator calculator uses Brush Power Drop = Armature Current*Brush Voltage Drop to calculate the Brush Power Drop, Power Drop in Brush DC Generator is the loss taking place between the commutator and the carbon brushes. The voltage drop occurring over a large range of armature currents, across a set of brushes is approximately constant. If the value of the brush voltage drop is not given then it is usually assumed to be about 2 volts. Thus, the brush drop loss is taken as 2Ia. Brush Power Drop is denoted by PBD symbol.

How to calculate Power Drop in Brush DC Generator using this online calculator? To use this online calculator for Power Drop in Brush DC Generator, enter Armature Current (Ia) & Brush Voltage Drop (VBD) and hit the calculate button. Here is how the Power Drop in Brush DC Generator calculation can be explained with given input values -> 4.3875 = 0.75*5.85.

What is Power Drop in Brush DC Generator?
Power Drop in Brush DC Generator is the loss taking place between the commutator and the carbon brushes. The voltage drop occurring over a large range of armature currents, across a set of brushes is approximately constant. If the value of the brush voltage drop is not given then it is usually assumed to be about 2 volts. Thus, the brush drop loss is taken as 2Ia and is represented as PBD = Ia*VBD or Brush Power Drop = Armature Current*Brush Voltage Drop. Armature Current is defined as the current developed in the armature of an electrical DC generator due to movement of rotor & Brush Voltage Drop refers to the voltage that is lost across the brushes and the commutator as the electrical current passes through them.
