Why dont birds die when they sit on an electric power line?

• They arent grounded

• arent heavy enough to make a good electrical connection

  
  

• their feet arent good insulators

  
  

• none of the above

  
  

what Happens when an additional resistor is added in a series with an existing series circuit?

• the total circuit current decreases

• the total circuit current increases

• the voltage drop accros the circuit increases

• none of the above

what is the power level that dissipates across a 5 resistor with a 20 Vdc power source?

• 100 watts

• 8 watts

• 80 watts

• 4 watts

vWhat is the main reason you should not engage in horseplay around high voltage electrical equipment?

• you might make one of your friends mad

  
  

• you might not have time to get your work done

  
  

• you might cause serious injury to yourself or others

• you might get in trouble

  
  

what is the effect you may feel called, when two parts of your body touches an energized circuit?

• a burning sensation

  
  

• an electric shock

  
  

• an electric short

  
  

• a static discharge

  
  

what does, the sum of the voltage drop across the resistors in any series string add up to.

• decreases if the source voltage increases

• the source voltage

• less than the source voltage

• greater then the source voltage

what form of ohms law is used to calculate the circuit current where voltage and resistance are wn

I=ER

I=PE

• I=PE

• I=R/E

• I=ER

• I=E/R

how is the Multimeter connected when measuring circuit current.

• to read only a portion of the circuit current

  
  

• so that all the circuit current flows through the meter

  
  

• across the power supply

• in parallel with any resistor
