Parallel choices

  1. 1. The Product-over-the-Sum Formula is best used when how many Loads are in parallel?1. Three2. Four3. Two4. None of the Above 0% 0% 0% 0% 1 2 3 4
  2. 2. When four Loads of equal value are in Parallel, the Total Resistance is1. Sum of all Four2. 25% of One Load3. Dependent on the Voltage4. The sum divided by two 0% 0% 0% 0% 1 2 3 4
  3. 3. The current through three parallel loads are 6A, 1.5A, and 300mA; what is the total current1. Less than 300mA2. 7800mA3. Have to know the Voltage first 0% 0% 0% 1 2 3
  4. 4. Four Resistors in Parallel: 3 are 1Mohms and one is 10 ohms, what is the Total Resistance?1. 3,000,010 ohms2. 333,343 ohms3. Between 10 and 15 ohms4. Less than 10 ohms 0% 0% 0% 0% 1 2 3 4
  5. 5. If a parallel circuit had 3 Loads, what would be the affect on Current if another Load was added in Parallel?1. Would not change if the Voltage remained the same2. The current would increase3. The current would decrease4. Depends on the size 0% 0% 0% 0% of the Load 1 2 3 4
  6. 6. If a parallel circuit added another Load in parallel, the total resistance would1. Increase2. Not change3. Change only if the Voltage changed4. Decrease 0% 0% 0% 0% 1 2 3 4
  7. 7. The sum of Current entering a point _____________ the Current leaving that point.1. Equals the sum of2. Drops3. Shares4. Develop a Voltage Drop 0% 0% 0% 0% 1 2 3 4
  8. 8. Seven Resistors are in Parallel with values of 10K,1000, 10K, 2000, .01M, 10,000, and 10K ohms. What is the Total Resistance of the circuit?1. 53K ohms2. 6K ohms3. 500 ohms4. 250 ohms 0% 0% 0% 0% 1 2 3 4
