have little or no electrical resistance. can be used for a long time. are not energy-efficient. can be made easily.
shunt high-resistance coil in the armature circuit low-resistance coil in the armature circuit shunt and a coil of high resistance
The voltage drop across each resistor is the same The total current flow equals the reciprocal of the sum of the individual currents The total resistance equals the sum of the individual resistances The total voltage equals the sum of the individual voltages across each resistance
With a flip of switch, electricity can be transmitted. Other American cities can benefit from the high-performance cables. Great amounts of power can be conserved. Detroit will first receive electricity transmitted by the new electrical cables.
increase in resistance with increased temperature increase in resistance with decreased temperature decrease in resistance with increased temperature increase in conductance with increased temperature
Copper. Liquid nitrogen. Clay. Calcium.
larger than the greatest branch resistance smaller than the lowest branch resistance equal to the sum of the individual branch resistances one-half the sum of the individual branch resistances
half the resistance of the other resistor a resistance equal to the other at least ten times the resistance of the other a partial short circuit
-143 degree Celsius. -263 degree Celsius. As long as it is ice-cold. Absolute zero.
