31. The START team began the "'Mega Ampere Spherical Tokamak "' 32. The radial current in the circuit is on the order of 3?0 9 amperes . 33. At 300 amperes of load current, the voltage would be . 0026 volts. 34. Conductor sections up to 2000 mm 2 may transport currents up to 2000 amperes . 35. But then, how come the Ampere reading. 36. As such, the SI unit of magnetic dipole moment is ampere meter 2. 37. A known ampere can then be used to calibrate instruments that measure other things. 38. The ampere too is defined relative to the newton, and ultimately, the kilogram. 39. A large solidly grounded distribution system may have thousands of amperes of ground fault current. 40. Using Ampere 's law, the toroidal plasma current can be determined as well.
