- Does Peak Voltage and Intrinsic Stand-off Ratio have dependency on other circuit parameters (such as voltage or current)? Explain your answer.Many prototype circuits need simulation. One web-based simulation software can be located here - Using this software, answer the following Scenario: The logic to control the remote tripping coil of a circuit breaker is as below. Four (4) different sensors – A (Overload), B (Inverse time) C (Breaker open), and D (Low current). If either A OR B are on AND if both C AND D are off then this will activate the coil (breaker open). No output must be given for any other combinations or conditions.
