Ohm's Law:

 

In the same circuit, the current in the conductor is proportional to the voltage across the conductor and inversely proportional to the resistance of the conductor.

 

Standard type: I=U/R.

 

The unit of physical quantity in the formula: I: (current) is in amperes (A); U: (voltage) in volts (V); R: (resistance) is in ohms (Ω).

 

Electric power formula:

 

P=UI

 

In the pure resistance circuit, according to Ohm's law U=IR substituted into P=UI can also be obtained: P=I2R=(U2)/R.

 

Product connection:

 

Constant voltage light bar: one end of the outlet is recommended to receive 5M; two ends of the outlet are recommended to receive 10M.

 

Constant current light bar: one end of the outlet is recommended to receive 10M; two ends of the outlet is recommended to receive 20M.

 

Product line:

 

Product outlet: The longer the outlet length, the thicker wire is recommended.

 

When the outgoing line is ≥ 2M, it is recommended to use a wire with a diameter of ≥ 0.5mm2 (20#).

 

When the outgoing line is ≥ 5M, it is recommended to use ≥ 1mm2 (16#) wire diameter wire.
