Introduction to Electronics and Electricity

Hydraulic System Pressure

• Pressure in a hydraulic system is equivalent to force per unit area, similar to how pressure is measured in other contexts.

Resistance and Current Flow

• Resistance in a circuit directly affects current flow, acting as an obstacle.
• Higher resistance leads to lower current, and vice versa.

Electrical Analogy to Fluid Power Volume

• Current in electrical systems is analogous to volume flow rate in fluid power systems.
• This means that the volume of fluid moving through a hydraulic system is analogous to the amount of electrical charge flowing through a circuit.

Direct Current

• Direct current (DC) provides a continuous flow of electrons in one direction.
• This is in contrast to alternating current (AC), which changes direction periodically.

Electrical Resistance Term

• The term for the restriction to current flow in a circuit is resistance.
• It is measured in ohms (Ω).

Voltage and High Resistance

• When voltage is applied to a circuit with high resistance, the current flow will be low.
• This is because the resistance restricts the flow of electrical charge.

Ohm's Law

• Ohm's Law describes the relationship between voltage, current, and resistance.
• It states that voltage (V) is directly proportional to current (I) and resistance (R).
• The formula is V = I x R.

Stationary Electric Motor Voltage Range

• Stationary electric motors in hydraulic systems typically operate within a voltage range of 24-48 volts (DC).
• The specific voltage used depends on the motor's design and the application.
