Finding the Total Voltage in a Series Battery Connection
Four 12V batteries connected in series, where the positive terminal of each battery connects to the negative terminal of the next. In a series connection, the voltages add up to produce a higher total output voltage.
Auto–Manual Float Switch ⚡💧
This circuit is used to control a 3-phase water pump with two modes:
🔹 Manual → The pump is turned on directly via the Start/Stop button.
🔹 Auto → The float switch in the tank operates automatically according to the water level.
Equipped with a contactor and overload relay for motor protection for increased safety and durability. 💡🔧
