Question

True or False:

1. Resistors connected in series always have equivalent resistance greater than any individual resistor.  

2. Resistors connected in parallel have equivalent resistance greater than any individual resistor.

3. Most materials have increased resistance as they heat up.

4. A battery's primary function is to provide charge and power to a circuit.  

5. The voltage difference between two points in the same (ideal) wire is ALWAYS 0.  

Answer 1

1) TRUE 4n series equivalent Resistance فر ' sum of indivial resistance EX R = 22 R2 = 32 keq = Ritra 2+3= sh. 21 R2 = 34 let ť, + FALSE in parallel Ri It 1 ti Req R 2*3 Req 2+3 TRUE As the tomp changes the dimension of the conduchor wolll change as it expand or condad in "conductor increase the temp worth increase the resistance 1 2 + 1 / e = 1.2.2 31 4 TRUE funchon in power supply bather & blow Current Primary current blow id moving change with time. 5) TRUE In ideal wire internal Resistance is Zero so benveen any point No voltage drop occur do Voltage difference in always o too
