STEP 0: Pre-Calculation Summary

Formula Used

Brush Power Drop = Armature Current*Brush Voltage Drop
P_BD = I_a*V_BD
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

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 P_BD 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 (I_a) & Brush Voltage Drop (V_BD) 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.

FAQ

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 P_BD = I_a*V_BD 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.

How to calculate Power Drop in Brush DC Generator?
