Electric wheelchair pays attention to capacity and voltage of 12V8AHVRLA batteriesCircuit features: The total voltage of both ends of the series circuit is equal to the sum of the voltage at both ends of the circuits. U = u1 + u2 + .. + un
In the parallel circuit, the voltage across the branches is equal. U = u1 = u2 = .. = un
4. Electric power: (1) Definition: Current intensive electrical power made in unit time. Expressed with symbol “P”. Significance: It is a physical quantity that represents a slow time.
(2) Unit: International unit – Watt (Wa) (W) Common units are also – kW (kW)
(3) Formula: Defined –P = W / T Determine -P = UI (because W = UIT = PT) Export -P = U2 / R = I2R (because P = Ui, I = U / R U = IR)
(4) Measurement: Voltammetry (Voltage Meter and Current Table) can also be measured by electric energy meter and stopwatch.
(5) Rated power and actual power: The usage of the appliance nameplate is usually rated voltage and rated power. If a lamp is marked with “PZ220-60”, “220V 60W”, etc., to know that R (because P = U2 / R so R = U2 / P), it can also be obtained from normal operation. Current I (because p = ui so i = p / u). The light of the lamp is determined to its actual power.
(6) Electrical power characteristics:
a. Electrical power characteristics: The total power consumption of series circuits and parallel circuits is equal to the sum of the power consumed by each appliance. That is p total = p1 + p2
b. Relationship between electrical power and resistance in series circuit: The power consumed by each electrical (resistance) in series circuits is proportional to its resistance. P1 / P2 = R1 / R2
C. Relationship between electric power and resistance in parallel circuit: The power consumed by each electrical (resistor) in parallel circuit is inversely proportional to its resistance. P1 / P2 = R2 / R1

“Responsible for the road cleaning work, Dujan, said. Combined with the comprehensive and health comprehensive rectification actions, all departments of Tongren County launched a series of special actions such as fighting, drying cereals, straw incineration along the road. At the same time, walk The village is promoted to the laws and regulations, carrying out the daily inspection system of environmental remediation, effectively promoting the stage of health remediation work in the county. There is less garbage, less noise, the households in the old street think that it is to walk, I did not expect the rectification It has been so long. “We lived in the old street in Longbao for a long time, and now the neighborhood is clean and refreshing. Last month, I was still in the old street entrance, I didn’t let the big car came in. Our living area is quiet, “Ms. Tie, Ms., is excited.
