There are some some of the laboratory laboratory laboratory laboratory laboratory laboratory laboratory laboratory laboratory laboratory laboratory laboratory laboratories Some, some some, some, some, some, some
a. The maximum resistance value of this resistor can be connected by 10Ω
b. The current in this variable resistor does not exceed more than exceed more than exceed, when it, it uses
c. When the voltage at both ends of the barrier does not exceed more than exceed, it is used, it uses it
D. When this resistor is used, it consumes the maximum power of 10W
Test: slide and slide. Essence Essence
analyze:
1 (1) Sliding and sliding resistor is marked with labeled labeled labeled labeled labeled labeled labeled labeled, 10Ω1A, 10Ω transformer connected circuit connected to the circuit. ; 1A represents 1A indicates that 1A represents 1A sliding 1A transformer 1A 1A. 1A. 1A. 1A. 1A. 1A. 1A. 1A. 1A. 1A. 1A.

2)) The maximum of sliding sliding resistor is based on P = I2R.
answer:
A, 10Ω means that the most connected resistance is the most resistant resistance resistance is 10Ω
B, the name of the nameplate indicates that the current of the sliding resistor can exceed more than more than exceeded. Essence Essence Essence Essence Essence
C. When the voltage voltage voltage voltage at both ends is changed, 10Ω, 10Ω, 1A current 1A. Essence Essence Essence If the access resistance is 1Ω
D, the maximum current that allows the sliding resistor is to pass the maximum. Is it 10Ω
So choose C.
